In Lord Hastings the boys had found an excellent friend. Although apparently but a commander of a small scout cruiser--unknown to but a very few--he was one of the most trusted of British secret agents. He was a distant relative of the English monarch and, as the boys had already learned, had more power in naval affairs than his officers and associates surmised. This fact had been proved more than once, when he had given commands to men apparently much higher in rank. Following the brilliant victory of the British fleet off Heligoland, in which a number of the Kaiser's most powerful sea fighters had been, sent to the bottom, the Sylph had returned to London for repairs. Here Frank and Jack had been personally presented to King George, who had thanked them for their bravery and loyalty and raised them to the rank of Fourth Lieutenant. Lord Hastings had been ill, but his illness had been of short duration; and so it was not long before the two lads once more found themselves pacing the deck of the Sylph, going they knew not where; nor did they care much, so long as it took them where there was fighting to be done. It was on the very day that the Sylph lifted anchor for her second cruise, that London heard of the prowess of the German cruiser Emden, a swift raider which later caused so much damage to British shipping as to gain the name "Terror of the Sea." The news received on the day in question told of the sinking of an English liner by this powerful enemy. When Frank and Jack sought to learn the destination of the Sylph from Lord Hastings, he had put them off with a laugh. "You'll know soon enough," he said with a wave of his hand. "Are we likely to see action soon?" asked Jack. "If we are fortunate," was the reply. "Well, that's all we wanted to know," said Frank. "Don't worry," replied His Lordship. "You will see all the action you want before this cruise is over, or I am very badly mistaken." And with this the boys were forced to be content. For two days they sailed about in the sunny Mediterranean, sighting neither friend nor foe, and then suddenly had encountered the two German cruisers, the Breslau and the Goeben, and the skirmish with these two ships, described at the opening of this story, ensued. But now, as the enemy had succeeded in making off in the darkness, and as Lord Hastings had ordered that the original course of the Sylph be resumed, the little vessel was again--as Jack said when they had started on their journey--"sailing under sealed orders." The two lads were about bright and early the morning following the encounter with the German cruisers; and as they stood looking out over the sea, Lord Hastings approached them. "More news of the Emden," he said, as he came up. "Another British merchant vessel sunk?" asked Jack. "Worse," replied Lord Hastings. "A cruiser this time!" "A cruiser!" exclaimed Jack in surprise. "I always thought that any cruiser of ours was more than a match for a German."
